Abstract

The utility model discloses a gravity pressure flow sediment ejector which ejects sediment in a water reservoir out of a dam. The gravity pressure flow sediment ejector is composed of a gravity pressure water pipe, a gravity pressure liquefying infiltration pipe, a gravity pressure block-slaking water filling pipe, a flow sediment ejecting pipe, etc., wherein flow sediment ejecting pipe, the gravity pressure liquefying infiltration pipe, and the gravity pressure block-slaking water filling pipe are laid on the bottom of a sediment accumulation layer in the water reservoir. An inlet port of the flow sediment ejecting pipe is positioned in a sediment accumulation zone, and the outlet port of the flow sediment ejecting pipe penetrates through a valve on a sediment hole of a dam and goes to the back of the dam. With the pressure force of water levels in the water reservoir, a water flow with sediment is forced to be ejected to the back of the dam through the flow sediment ejecting pipe. In order to keep sediment in the dam in a liquefied state, water in the gravity pressure water pipe is infiltrated into alluvial sediment through the gravity pressure liquefying infiltration pipe. When the flow sediment ejecting pipe is blocked, the gravity pressure block-slaking water filling pipe is opened, and water in the gravity pressure water pipe is filled into the flow sediment ejecting pipe through the gravity pressure block-slaking water filling pipe to regulate the concentration of ejected sediment and solve the block problem. The gravity pressure flow sediment ejector has low sediment ejecting cost and high sediment ejecting efficiency.

Description

Moisten the stream sand discharge apparatus from pressure

One, technical field: the utility model relates to the silt clearance technique field in the reservoir, is that a kind of the pressure certainly moistened the stream sand discharge apparatus.

Two, background technology: now reservoir As time goes on, a large amount of gradually shoal materials in bottom of the reservior make pondage reduce thus, even face and scrap, so must in time remove.Remove that the method for silt is most to adopt the waterpower sand surfing that reduces reservoir level or with mechanical dredging methods such as dredge boats, these method water consumption are big, efficient is low and the cost height present stage.

Three, summary of the invention: order of the present utility model is not enough in order to overcome in the prior art, provides a kind of self-pressure that silt in the reservoir is discharged to outside the dykes and dams to moisten the stream sand discharge apparatus, with this device remove silt efficient height, cost is low.

In order to achieve the above object, realize by following technical proposals:

Self-pressure is moistened the stream sand discharge apparatus, is moistened stream silt pipeline and is formed by the stifled water injection pipe that disappears from pressure pipe, self-pressure liquefaction soakaway trench, self-pressure, row.Row is moistened stream silt pipeline, self-pressure liquefaction soakaway trench, the self-pressure stifled water injection pipe that disappears be laid on reservoir sediment accumulation layer bottom, row is moistened stream silt pipeline one end and is passed from the husky hole of the following row of dykes and dams gate, leads to the outside of dykes and dams.Moisten the stream pipeline exit row gate valve is set; Self-pressure cross current self-pressure liquefaction soakaway trench and the self-pressure stifled water injection pipe that disappears.From the hydraulic fluid soakaway trench with press the stifled water injection pipe that disappears to pass the dam body end and gate valve is set respectively certainly from the pressure pipe connecting portion.

By the infiltration of self-pressure soakaway trench, can make the liquefaction of Sediment Siltation layer bottom sediment, form to moisten to flow to into row and moisten stream silt pipeline, realize the purpose of unblocked discharge silt.

For stream silt line clogging is moistened in the row of preventing, moisten the water filling of stream silt pipeline by the self-pressure stifled soakaway trench that disappears toward row, can eliminate obstruction.Disappear stifled soakaway trench and row of self-pressure moistened and flowed the silt device for cleaning pipeline and cross water injection pipe and chew and be communicated with, and connectivity points is more than 3 o'clock.

Self-pressure liquefaction soakaway trench described in the utility model must the row of being longer than moisten stream silt pipeline more than 0.1 meter, and will often open, in order to make shoal materials liquefaction, forms and moistens stream silt, is convenient to discharging.

Four, description of drawings

Accompanying drawing 1 is a structural representation of the present utility model.

Five, the specific embodiment

Moistening the stream sand discharge apparatus by self-pressure shown in Figure 1 comprises from disappear stifled water injection pipe 3, row of pressure pipe 1, self-pressure liquefaction soakaway trench 2, self-pressure and moistens stream silt pipeline 4.After pressure pipe 1 was located at the dam, the upper end was passed dykes and dams top and is stretched in the water of storehouse, the lower end with disappear stifled water injection pipe 3 and connect from hydraulic fluid soakaway trench 2.Row is moistened stream silt pipeline 4, self-pressure liquefaction soakaway trench 2, the self-pressure all parallel Sediment Siltation layer bottoms that be embedded in of stifled water injection pipe 3 that disappear, and an end passes dam body through arranging husky hole gate 8.Open valve 5, by self-pressure liquefaction soakaway trench 2, toward the infiltration of Sediment Siltation layer, shoal materials is formed moisten stream silt, open valve 7 and can arrange sand.When row is moistened stream silt pipeline 4 and is stopped up, open valve 6 and moisten 4 water fillings of stream silt pipeline by the self-pressure plugging 3 that disappears toward row, can eliminate obstruction.
